A report of a clinical trial of a new drug versus a placebo noted that the new drug gave a higher proportion of success than did the placebo. Accompanying this finding was the statement chi-square test statistic = 4.72, with a p<0.05. In light of this information, we may conclude:

Fewer than 1 in 20 will fail to benefit more from the drug than the placebo.

Fewer than 1 in 20 patients will benefit more from the placebo than the drug.

The probability of treatment success is less than 5% for a patient given the drug.

If the drug were effective, the probability of the reported finding is less than 5%.

If the drug were ineffective, the probability of the reported finding is less than 5%.
